Abstract

Software, resident or a host computer, that is capable of parsing a data stream of multiple interleaved data signals into the individual data signals that are then ready for manipulation and further processing by the host computer.

Claims

1. A method for parsing an interleaved multiple data stream into the individual data streams contained in the interleaved multiple data stream, said method comprising the following steps:

(a) determining the data type and other parameters of each of the individual data streams contained in the interleaved multiple data stream;

(b) calculating the data ratios for each individual data stream contained in the interleaved multiple data stream;

(c) receiving the interleaved multiple data stream, any individual data stream contained in said interleaved multiple data stream may be compressed;

(d) copying each line of the individual data streams into predetermined buffers;

(e) performing decompression on any individual data stream as necessary;

(f) switching between the individual data streams based on the data ratios calculated in step (b) above; and

(g) returing to step (c) until the interleaved multiple data stream is completed.

2. A method for parsing an interleaved multiple image data stream into each individual view contained in the interleaved multiple image data stream, said method comprising the following steps:

(a) determining the data type and other parameters of each individual view contained in the interleaved multiple image data stream;

(b) calculating the image ratios for each individual view contained in the interleaved multiple image data stream;

(c) receiving the interleaved multiple image data stream, any individual view contained in said interleaved multiple image data stream may be compressed;

(d) copying each line of the individual views contained in the interleaved multiple image data stream into predetermined buffers;

(e) performing decompression on any individual view as necessary;

(f) switching between the individual views contained in the interleaved multiple image data stream based on the image ratios for each view calculated in step (b) above; and

(g) retuning to step (c) until the interleaved multiple image data stream is completed.
